Doi:10.1001/jama.2020.10224 In a study published in the international journal JAMA, scientists from Massachusetts General Hospital and others conducted the largest study of its kind to date and found that vitamin D supplementation may not prevent depression in middle-aged and older people.
is a long-standing problem that may prompt some people to take vitamins.
that vitamin D supplements may not have significant benefits and may not prevent depression or improve mood.
researcher Okereke said the study included more than 18,000 men and women aged 50 and over, half of whom received vitamin D3 (cholecalciferol) for an average of five years, while the other half received a placebo matched at the same time.
Vitamin D is sometimes referred to as a "sunshine vitamin" because the skin naturally synthesizes vitamin D when exposed to sunlight, and previous studies have shown that lower levels of vitamin D (25-hydroxyvitamin D) in the blood are associated with an increased risk of depression in later life, but few large-scale randomized trial studies have determined a causal link between the two, and now researchers have given a clear answer.
: J Psych Neurosci: Suffering from anxiety and depression at the same time may make the brain larger Doi:10.1503/jpn.190156, published in the international journal Journal of Psych and Neuroscience In a study entitled "Volumetric brain differences in clinical depression in association with anxiety: a system review with meta-analysiss", scientists from institutions such as the Australian National University have found that depression may be associated with the size of an individual's brain atrophy region, but when depression is associated with anxiety, this area of the brain becomes significantly larger. In
article, researchers studied more than 10,000 participants to reveal the effects of depression and anxiety on the body's brain capacity;
, the researchers found that when depression and anxiety occur at the same time, they increase the size of the mood-related areas of the brain, the amygdala.
3: Why do probiotics and probiotics help protect against anxiety and depression? doi:10.1136/bmjnph-2019-000053 After researchers linked mental health problems and developmental disorders directly to intestinal health, scientists from institutions such as the Brighton and Sussex School of Medicine in the United Kingdom found that food may be able to expand levels of beneficial bacteria in the gut to help reduce body anxiety and depression more easily, according to a study published in the international journal BMJ Nutrition Prevention and Health.
paper, researchers aim to determine whether foods containing bacteria that can have a positive impact on the gastrointestinal microbiome can influence treatments for mental illnesses such as anxiety and depression.
Trillions of microbes live in the body's digestive tract, and there are at least 400 bacteria in the body's intestines, which means that there are far more bacteria in the gut than in the body's cells, which are essential for digesting food, protecting against potential pathogens or harmful microorganisms, and synthesized vitamins.
According to research by the UK's National Centre for Complementary and Integrated Health, researchers have long known that there is a mechanism of communication between the brain and the gut, but recent studies have found that the two are a two-way link, in addition to the gut bacteriologies that affect the body's behavior and mood, which in turn affect the chemical properties of the brain, changing intestinal bacteriologic levels through a special diet or helping to treat stress-related and neurodevelopmental disorders such as autism and ADHD.
. JAMA Psych: Depression or a direct association with an increased risk of cardiovascular disease and premature death Doi:10.1001/jamapsychiatry.2020.1351 In a study published in the international journal JAMA Psych, scientists from Simon Fraser University and others have revealed a link between depressive symptoms and an increased risk of heart disease and early death. In the
article, researchers followed 145,862 middle-age participants from 21 countries and found that participants with four or more symptoms of depression had a 20 percent increased risk of cardiovascular events and death, double the risk in urban areas, and more than double or more risk for male participants, with the majority of the world's population living in urban areas by 2050.
Depression and mental health problems are very prevalent in Canada, with one in five Canadians experiencing mental health problems through their lifetime and about 8 percent experiencing severe depression, and researcher Lear said the findings are timely because experts speculate that the number of people dealing with mental health problems later in life should increase because of the prevalence of COVID-19.
: Mol Psych: Shocked! Fish oil could help treat depression! doi:10.1038/s41380-020-0786-5/!-- ewebeditor:page--!--ewebeditor:page title"--a study published in Molenecular Psythony shows that adult stem cells from patient sources can be used to simulate depression and test patients' responses to drugs.
at the University of Illinois at Chicago (UIC) studied stem cells from adults clinically diagnosed with depression and found that fish oil produced an antidepressant response when tested in a model.
study could help scientists better understand how the brain works and why some people respond to medication for depression, while others have limited benefits from antidepressants, the researchers said.
The scientific evidence that fish oil -- an easily available natural product -- may be an effective drug for depression is also exciting," said Rasenick, a distinguished professor of physiology, biophysics and psychiatry at UIC Medical School.

READ: Why teen depression rates are rising faster for girls than boys We are at the centre of a mental health crisis for teenagers, and girls are one of them; since 2010, depression, self-harm and suicide rates have risen among teenage boys, but in the US, teenage girls are heavier The incidence of depression rose from 12 per cent in 2011 to 20 per cent in 2017, and in 2015 girls aged 10 to 14 were three times more likely to enter emergency rooms for intentional self-harm than in 2010.
same time, the suicide rate among adolescent girls has doubled since 2007.
with the popularity of smartphones, the incidence of depression began to rise, so digital media may also play a role.
generation of teenagers born after 1995, known as iGen or Gen Z, were among the first to spend the entire adolescence of the smartphone age, and they were among the first to experience social media as an integral part of social life.
, boys and girls start using smartphones almost at the same time.
, why do girls have more mental health problems? After three surveys of more than 200,000 teenagers in the United States and Britain, the researchers found some answers.
researchers found that teenage boys and girls spend different hours on digital media, boys spend more time on games, and girls spend more time on smartphones, texting and social media.
games include different forms of communication, and gamers often interact in real time and communicate with each other through headphones.
, social media usually sends messages through pictures or text;
men living in poor areas may be more likely to suffer from severe depression! News Read: Depression: Depression Men far more at risk than women in deprived areas Depression is a major cause of disability in the global population, and failure to treat it promptly can lead to substance abuse, anxiety, and even suicide.
Severe depression is a particular disease that affects many people and can lead to loss of pleasure in activities that were once used to produce happiness, as well as useless, unbalanced effects such as oversleptness or insomnia, and trigger suicidal thoughts, researchers have found, and living in poor areas can lead to severe depression in men but not in women.
Before we can explain these findings, we need to provide background information about depression, and there are many factors that can lead to an increased risk of weight depression, both now and in the past, when individuals diagnosed with severe chronic diseases, such as diabetes or cancer, increase the risk of depression, as do traumatic experiences (such as physical or sexual abuse) or growing up in highly disharmonious families."
However, these personal factors or personal environment can negatively affect the body's mental health, and most depression-related studies focus on individual factors, but in addition to personal factors, there are a number of factors that affect the individual's risk of disease, such as the conditions in the areas where we live, will have a profound impact on the body's mental health.
Previous studies have shown that living in poor communities can lead residents to believe that they are in poor condition and experience early death, and by studying whether living in poor areas affects the mental health of men and women, even when considering their socioeconomic status, does a person's living environment really affect their mental health? Dermatitis: Depression in Pregnant Women and ??? Pediatric specific dermatitis-related doi:10.1097/DER.0000000000548 According to a new study published in the journal Dermatology, postpartum and even further meditative depression in mothers is associated with the development of endexual dermatitis AD throughout childhood and adolescence.
it is also closely related to many mental health disorders such as depression, anxiety and suicidal thoughts.
the study, led by Jonathan Silverberg, an associate professor of dermatology at George Washington University School of Medicine and the School of Health Sciences, looked at the relationship between postpartum depression and childhood AD.
, senior author of the study, said: "We know that emotional factors exacerbate AD seizures and affect the progression of the disease.
previous studies have shown that the family environment and other environmental factors may have an impact on AD.
"9" 2019AHASS: Individual levels of depression are closely related to the body's risk of cardiovascular disease News Read: Strong link found between levels of depression and heart disease, and at the upcoming 2019 American Heart Association conference in Philadelphia, researchers from the United States will report their latest findings that the severity of depression in a person may increase their risk of heart disease or stroke.
Researcher Dr. Joseph M. Khan said the body's cardiovascular health is often affected by a variety of factors, and it is also associated with a number of health aspects, including mental health.
We found a strong correlation between depression levels and heart disease and stroke risk, even after taking into account other factors that affect the risk of the disease, including the American Heart Association's ideal cardiovascular health guidelines, age, income, education, gender, and race.
!--/ewebeditor:page--!--ewebeditor:page title" -- Researchers studied U.S. adults 20 years and older and analyzed the association between depression and non-fatal heart disease, which includes heart failure, coronary heart disease, angina, heart attack and stroke.
using a depression questionnaire from the National Institutes of Health and Nutrition (NHANES), researchers identified more than 11,000 adults with depression, of which about 1,200 would be diagnosed with a heart attack or stroke.
